Nu-Air semi-pneumatic tiresNu-Air semi-pneumatic tires are designed to provide the durability of solid tires with the cushioned ride of pneumatic tires. The all-terrain tires can be used in on- and off-road applications — even in severe cutting conditions. The deep tread pattern provides optimal traction. Nu-Air tires have three to five times the life expectancy of pneumatic tires, says the company.
